Product Advantages
Full Redundant Architecture: Triple redundancy with dual processors, dual Vnet/IP networks and dual power supplies. Automatic switchover upon faults eliminates single points of failure.
Long-term Data Protection: Built-in backup battery keeps data stored for up to 72 hours after power loss, and full charging takes only 48 hours.
Powerful Computing & Large Memory: Equipped with dual 64-bit RISC processors and standard 128MB DDR3 RAM, capable of running complex control algorithms.
Industrial-grade Reliability: IP20 protection rating, wide operating temperature range (0–50°C) and vibration resistance for harsh industrial environments.
Seamless System Integration: Natively compatible with CENTUM VP. It supports FIO field I/O and Gigabit Ethernet-based Vnet/IP for flexible networking.

FAQ
Q1: What is the difference between AFV30D‑A41152 and AFV30S?A1: AFV30D is a duplex redundant model with redundant CPU, network and power supply. AFV30S is a simplex model without redundancy. The D model is applied to critical control loops, while the S model is for non-critical scenarios at a lower cost.
Q2: How is the 72-hour battery backup calculated?A2: At an ambient temperature of 25°C, after being fully charged for no less than 48 hours, the battery can retain RAM data and programs for up to 72 hours during power outage. The backup duration decreases as the temperature rises.
Q3: Can it be installed in hazardous explosive areas?A3: Standard models with suffix 5 have no explosion-proof certification. ATEX explosion-proof options (suffix E/F) are available for installation in Zone 1/2 hazardous areas.
Q4: What is the redundant switchover time? Will data be lost?A4: Network switchover takes ≤50ms and CPU switchover ≤100ms. No data loss occurs. The control logic operates seamlessly with no impact on production.
Q5: Which versions of CENTUM VP are compatible?A5: Suffix 2 indicates compatibility with R6.01 and above. For older R5.x versions, please select models with suffix 1. Confirm your system version before ordering.
Q6: How many I/O modules can be connected?A6: It supports a maximum of 8 I/O modules. Up to 13 node units (ANB10/ANB11) can be connected via the ESB bus for flexible expansion.
